Some old pics of the rare Utricularia costata

Recommended Posts

Hello everyone,

A friend recently posted pics of a beautiful array of CPs growing in coastal habitats of the state or Rio Grande do Norte, in NE Brazil (http://www.carnivora...l-t3529-70.html), including the first ever collections of U.viscosa and U.costata for NE Brazil, as well as a few other rare and recently discovered species for that region such as U.resupinata and U.cornuta.

After seeing the above pics, another friend mentioned that he had never seen pics of the rare U.costata before. This species is very widespread but was only known to Peter Taylor in his Utric monograph from a few collections, including the type location in Bolivar state, Venezuela, and in the Brazilian states of Roraima, Pará, & Mato Grosso.

Since that publication in 1989, I have seen U.costata at two sites: one in S Mato Grosso and one in S Goiás (1st for that state). Other friends have since found another site in S Mato Grosso (http://www.plantasca...hp?f=27&t=10094) and S Goiás (http://www.plantasca...php?f=27&t=7209).

The above suggests that U.costata is probably more common than we think, but is probably undercollected due to its diminutive size, being often overlooked by botanists.

Anyway, I just ran across some old pics of U.costata I took back in April/May 1999. Due to the rarity of this species, I decided to scan them and post here, even if bad quality. :)

This was the site I found in S Goiás, near the town of Jataí. It was a surprisingly huge population (the site I'd seen in M.Grosso was a frustratingly tiny little patch). As you can see from the pics below, the flowers were not packed tight, but at least they were common over a large area. Let's see how many you can count! :)


Here's a close-up where you can even see someU.costata leaves:


Taking the opportunity that this was such a big population, I decided it would be botanically important to make a large herbarium collection:



It was a lot of work spotting and picking all those scapes, but I think future botanists will appreciate it. :)

Best wishes,

Fernando Rivadavia
